Compara����o do efeito da fadiga muscular no andar livre e adaptativo entre adultos jovens e idosos

A fadiga muscular �� definida como uma falha no sistema neuromuscular na capacidade de gerar uma for��a requerida ou esperada. Quanto maior a idade do indiv��duo, maior �� a probabilidade de chegar �� fadiga, aumentando o risco de quedas. Dessa forma, a fadiga pode influenciar no andar dos indiv��duos, causando preju��zos no controle postural e podendo causar les��es m��sculo-esquel��ticas A partir dos estudos realizados, percebe-se que a fadiga muscular pode prejudicar o desempenho do andar, sendo ele adaptativo ou n��o. O objetivo do estudo foi analisar e comparar a influ��ncia da fadiga muscular sobre os par��metros cinem��ticos do andar livre e adaptativo entre adultos jovens e idosos. Participaram do estudo 20 indiv��duos, distribu��dos em dois grupos et��rios: Adulto Jovem - 20 a 40 anos; e Idoso - a partir de 60 anos. Os participantes realizaram o andar livre e adaptativo percorrendo uma dist��ncia retil��nea de 8 metros sobre um carpete de borracha com 1,4m de largura. Foram realizadas 6 tentativas para cada condi����o experimental. Para a coleta dos dados cinem��ticos dos ciclos do andar definidos foi utilizado um sistema tridimensional (3D) optoeletr��nico de an��lise do movimento (OPTOTRAK Certus ��� 3D Motion Measurement System, NDI), com precis��o de 0,1 mm, posicionado no plano frontal, face anterior, ao movimento do participante, com frequ��ncia de 100 Hz. A indu����o a fadiga ser�� atrav��s da tarefa de sentar e levantar. Para a compara����o entre os dois grupos foram analisados as seguintes vari��veis espaciais e temporais do andar livre e adaptativo: comprimento de cada passo, largura de cada passo, velocidade m��dia do andar, dist��ncia horizontal p��-obst��culo antes da ultrapassagem, dist��ncia horizontal depois do obst��culo e dist��ncia vertical p��obst��culo. Estas vari��veis foram analisadas durante o ciclo do andar antes e ap��s fadiga muscular.

Uma op����o terap��utica para o aumento da faixa de gengiva inserida: o enxerto de tecido conjuntivo livre

Several periodontal procedures have been described in the literature to correct mucogingival alterations or to achieve root coverage. The epithelized free gingival graft is a well established periodontal surgery to increase the width of keratinized gingiva with good stability in the long term follow up. However, this procedure is not commonly used in aesthetic areas since the grafted tissue presents differences of color and contrast. The free connective tissue graft emerges as a viable option to increase attached gingiva in areas where aesthetics results are required. The removal of an epithelized free gingival graft from the hard palate region creates a sore and raw surgical wound that slowly repairs, while the connective tissue graft produces only a line of incision that can be easily sutured promoting a more confortable outcome for the patient. This paper aims to report a case where a free connective tissue graft was used to increase the width of attached gingiva in a tooth with gingival recession. This technique presented satisfactory esthetics results, with a better contrast and color matching with the surrounding tissues.

O paciente decide submeter-se a um tratamento, fornecendo o seu Consentimento Livre e Esclarecido com base nos dados a ele apresentados. Infelizmente, pode ocorrer de alguns profissionais n��o fornecerem todas as informa����es necess��rias a uma tomada de decis��o esclarecida ou, depois de obtido o consentimento do paciente, apresentarem-lhe informa����o que cause sua desist��ncia do tratamento inicialmente aceito. Esta ��ltima informa����o, se pertinente, e n��o se tratando de fato superveniente, deveria ter sido fornecida inicialmente. Por��m, a informa����o pode n��o ser de todo verdadeira, e levar o paciente a decidir baseado, por exemplo, em riscos apresentados e mensurados de forma equivocada. A reabilita����o cr��nio-facial da Articula����o T��mporo-Mandibular (ATM), por meio de pr��tese de ATM, �� indicada em muitas situa����es. Ami��de, pacientes que necessitam de tais pr��teses apresentam problemas funcionais e est��ticos; a expectativa gerada com a reabilita����o �� grande. Este trabalho apresenta um caso e discute quest��es ��ticas e legais, incluindo a responsabilidade civil, do fornecimento parcial e inadequado de esclarecimentos a um paciente.

Bombeamento e tratamento da fase livre em Aqu��fero Litor��neo

High fuel consumption and its inadequate control in fuel stations caused the pollution of soil and aquifers. These consequences created more concern with the increased exploration of aquifers to supply the groundwater demand. The objective of this study was to evaluate the eficiency and efectiveness of the of pump and treat technique of the water applied to the Coastal Aquifer in the cleaning up of the plumes produced by the leaking of fuel in the gas station Auto Posto Ba��a do Sol Ltda. The gas station is located in S��o Sebasti��o, in the north coast of S��o Paulo State. In the case of Auto Posto Ba��a do Sol Ltda., the technique of pump and treat was eficient and the plume produced by the leakage was completely removed. However, the efectiveness of this technique was low due to the long time required for the complete operation.

Fatores biomec��nicos relevantes na sele����o dos grampos em pr��teses parciais remov��veis com extremo livre: estudo cl��nico

The free-end removable partial dentures (RPD) shows a complicated and peculiar biomechanical behavior that impose high occlusion forces to the abutment teeth. By this way, the aim of this study was to evaluate the several factors that influence the clasps indication to free-end RPD. It was analysed 84 designed and planned study models of 71 patients, involving 130 clasps near-by a free-end; followed by clinical and radiographical informations. It was observed that bar clasps (���T���, ���Tmod���, ���i���) were used in 88.46% of abutment teeth. In the others (11.55%), it was used simple, combinated or ring circumferential clasps, and MDL. In abutment teeth with high equator line the ���i��� clasps were predominant (48.48%). The ���Tmod��� clasps were predominant in abutment teeth with low equator line (50%) or in middle third (51.35%) and ���T��� clasps were predominant in inclined equators with mesio-buccal (56.52%) or disto-buccal (66.66%) retention. In the posterior abutment teeth, it was prevalent the distal rest (63.52%) and embracing to the adjacent tooth. Some others factors like long clinical crown (5.38%), wrong position of abutment teeth (4.61%), aesthetics (3.07%), retention in alveolar ridge (2.3%), fragility of abutment teeth (1.53%), short clinical crown (0.76%) and short space to the clasp (0.76%) influenced directly during the clasps selection. Factors like mobility of abutment teeth, height of muscular insertions, depth of buccal fornix and antagonist arch acted like secondary factors. After the informations analysis it may be concluded that the bar clasps with distal rest and embracing to the adjacent tooth were the most indicated to free-end RPD

Reabilita����o Oral: pr��tese livre de metal, Remov��vel e implantes. Um caso de 12 anos de acompanhamento

The literature has suggested that the association of removable partial dentures with dental implants can improve the quality of life of patients. Thus, the purpose of this study was to present a case report. This case report describes the development of a removable partial denture associated with dental implants bilaterally been monitored for 12 years, and the efficacy of the proposed treatment. The radiographic controls demonstrated no changes on bone tissue. The maxillary arch was rehabilitated with metal-free crowns. The patient was fully satisfied with this technique providing stability, esthetics, and proper function. It was concluded that the technique of using removable partial dentures associated with dental implants is viable and show the advantages of improved function, aesthetics and cost reductions in rehabilitation treatment.

Influ��ncia do formato do rebordo alveolar sagital em reabilita����es com associa����o de pr��tese parcial remov��vel de extremidade livre e implante ��sseo integrado

The association of mandibular distal extension removable partial dentures with an osteointegrated implant is a treatment option at hasn't been fully explored by modern rehabilitation dentistry yet. The objective of this study is to evaluate, by means of the bidimensional method of finite elements, the distribution of tension on the structures supporting the distal extension removable partial denture (DERPD), associated to a 10.0 x 3.75 mm osteointegrated implant with an ERA retention system, in alveolar ridges of different shapes. Eight models were created, representing, from a sagittal perspective: Model A (MA) ��� a half arch with a horizontal ridge without posterior support, with the presence of the lower left canine, and a conventional DERPD, with metallic support in the incisal aspect of this canine, as replacement for the first and second pre-molars and the first and second molars of the lower left half arch; Model B (MB) ��� similar to MA, but different because of the presence of a 3.75 x 10.00 mm implant with an associated ERA retention system in the posterior region of the DERPD base; Model C (MC) - similar to MA, however with a distally ascending ridge format; Model D (MD) ��� similar to MC, but different because there is an implant associated to a retention system; Model E (ME) - similar to MA, however with a distally descending ridge format; Model F (MF) ��� similar to ME, but ditfferent in the sense that there is an implant with an associated ERA retention system; Model G (MG) ��� similar to MA, however with a distally descending-ascending ridge format; Model H (MH) ��� similar to MG, but different in the sense that there is an implant with an associated ERA retention system. The finite element program ANSYS 9.0 was used to load the models with vertical forces of 50 N, on each cuspid tip. The format of distal descending edge (ME and MF) was that presented worse results, so in the models with conventional RPD as in the models with RPD associated to the implant and ERA system of retention, for the structures gingival mucosa and tooth support. 1) the distally descending ridge presented the most significant stress in the model with the conventional RPD (ME) or with a prosthesis associated to an implant (MF) and 2) the horizontal ridge (MB) provided more relief to the support structures, such as the tooth and the spongy bone, when there was an implant associated to an ERA retention system. The incorporation of the implants with the ERA system retention, in the posterior area of the toothless edge, it promotes larger stability and retention to PPREL, improving the patient's masticatory acting and, consequently, its comfort and function.
